BOOT OR SHOE CRllVlPlNG MACHINE.

SFECIFICA'IION forming part of Letters Patent No. 295,187, dated March1S, 1884.

Application Fried b'ovcniber G, 1883.

-in the Province o Ontario, in the Dominion of Canada, have inventedcertain new and useful Improvements in Boot and Shoe Crimping Machines;and I do hereby declare that the following is a full, clear, and exactdescription ofthe saine.

My invention relates to improvements on my crimping-machine patentedMarch 21,1882, No. 255,178, in which one piece ot' leather is crimped tomake the seamless upper-leather for boots and shoes. the aperture forthe admission of the foot being afterward slitted or out out; and myinvention has for its object to improve the construction of the machine,whereby crimping can be effected more expeditiously and in a bettermanner.

My inventionconsists in the consti notion of afraine having removableand adjustable parts to adapt the machine to crimp for various sizes ofbootsand shoes by using molds of different sizes; also, in confining thehalved moldblocli between rubber plates by clamp-screws and interveninginfiexible plates, whereby the halved bloeit willyield to crimp leatherof different thicknesses; also, in providing the halved block with arubber cushion inserted at the toe to prevent abrasion ol'r the leatherin crimping, and in a curved plate inserted at the heel to cause theleather to be smoothly crimped; also, in a pressure or covering plateover the halved block to keep the leather smooth and regulate itsadmission between the halved and last blocks While crimping.

Figure 1 is a plan of my machine, the top partly broken away to show thecrimpingblocks. Fig. 2 is a side elevation of the same. Fig. 3 is afront elevation. Fig. 4 is a transverse vertical section. V Fig. 5 is atop view of the halved block detached. Fig. Gis a sectional elevation ofonevhalf of the saine, and Fig. 7 is a plan of the covering-plate.

A A are the sides of the machine; B, the bottom floor, notched into thesides and secured by bolts C and nuts D.

E are bolts passing through the sides near the top, and are providedwith nuts F, to preo vent the sides from s )readin of. 5 e

is a fixed bloot: closing one end ofthe machine,the opposite end open toadmit the halved block, hereinafter referred to, and which open end isprovided with agate, L, pivoted in one of the notches, J K, in anextended portion of the side A, and falls into a corresponding notch inthe oppositeside, whereby the gate, when adjusted in the proper notchand closed, prevents an endivise movement of the block and allowscrimping-blocks of difterentlengths to be used to crimp dii'ierent sizesof upperleathers. Y

M M are 'thumb-screws in one of the sides A, to' clamp the halved blockN, each half having a coinciding recess, O; and P is the lastblock,entering the recess to crimp the leather to the form of said block P.The heel-joint of the halved block N is covered by a'correspondingly-curved metal plate, Q, the vertical edges sliding into cutsin said blocks, which are recessed at top to receive flush the bentovertop of plate Q, and which serves to prevent the halves of the blockmoving endwise independently; but the main object of the plate Q, is toprevent creasing and abrasion of the leather in crimping, by causing itto slip smoothly between the crimping-blocks. The halved block N at thetoe is recessed at the joint to receive a rubber cushion, R, to preventabrasion of the leather While being crimped. Y

S S are rubber plates outside block N, and T are wooden plates outsideplates S, to nll the spaces between plates S and Vmetal plate U and theside A, against which plate U the clampsorews M M impinge and preventthem injuring the Wooden plate when the pressure of the screws isapplied to clamp the plates and blocks together. sufficiently underpressure to accommodate leather of different thicknesses.

V is a plate centrally hung to the end of the pressure-screw H, and isprevented from wabbling by braces W W, secured to the ends of the plateand bent upv through staples inA bridge G. The plate Vis provided withdove tail grooves to receive dovetail rails V on the The rubber plates Syield' IOO sole of the last-block P, to allow the latter to beslidingly. removed and another size substituted when desired.

Y is a metal plate, having an opening corresponding to the sole of thelast-block P, and Said plate is notched at one end to slide under thehead oia screw-button, Z, in. the Atop of block I at the end of themachine. Theopposite end of plateY is held down by pressure of a block,Z', secured to the'inside of gate' L, and When the dampened leather isplaced between the plate Y and top of halved block N the former willhave sufficient pressure to keep the leather smooth while being drawndown- Ward by the last-block in crimping, and therebyproduce an evensurface, free from creases. .The -bar or bridge. G is movable laterallyto allow thepoint ofthe screw to be central with kthe halved block,whereby blocks-of different sizes can be used with one machine.

. G7 are set-screws to fasten the bridge invpoysition.

L -is a pin vfor holding down gate L lloy in- `sertion of anintermediate wedge, 2.

3. The combination, with the notched'sides A A, ofthe adjustable gate L,provided with block Z', pin L', and wedge 2, for holding down one endotl plate Y, as set forth.

- 4. In combination With the halved block N,

having recesses O, the correspondingly-apertured plate Y, covering saidblock, and re movably secured to hold down the leather over theblock-orifice in crimping, as set forth.

for the purpose described.

` 7. The combination, in a crimping-machine provided with pressure-screwH. ofthe clampingsorews M M, halved block N, `and rubber yplates S, toyield to the enforced pressure of the last-block I), whereby leather ofdifferent 55 thicknesses may be crimped, as set-forth.
